I only collect chips with face values below $5 (with the occasional $5 chip thrown in), but I have been following Aruba chips on ebay closely for a few years. Larger denomination Concorde chips don't show up on ebay too often. I'm not sure I have seen any.

The only price guide for Aruba chips is pretty old, so the prices are somewhat out of date (it is a terrific book, nonetheless and I highly recommend it to Caribbean chip collectors), but your chips have some value. The value of the $25 and $100 will have about the same value (much below face) according to the book, but you don't see them too often, so they may be worth a bit more. There is a valuable version of the $25 chip. If you can scan the chips or take a picture and send them to me by e-mail, I can tell you if you have the rarer version.

Ultimately, the best way to judge the value is to put them up for auction on ebay.
